A filter apparatus for treating water containing particulate or microbial contaminants is provided. The filter apparatus includes a first filter element, such as a viral membrane, disposed within a sealed outer housing and in fluid communication with a first inlet port and a first outlet port. The first filter element is capable of treating water at a first flow rate and is adapted to remove contaminants that are larger than a first contaminant size. A second filter element, such as a bacterial membrane, is disposed downstream of the first filter element in fluid communication with a second inlet port and a second outlet port. The second filter element is capable of treating water at a second flow rate higher than the first flow rate and is adapted to remove contaminants that are larger than a second contaminant size. The second filter element may be housed within the sealed housing to form a multi barrier, replaceable filter unit. The unit includes a first inlet and a first outlet communicating with one of the filter elements and a second inlet and a second outlet communicating with the other filter element. The housing defines four ports arranged in substantially linear, side-by-side relationship which are adapted to establish fluid connections between the filter cartridge and a manifold forming part of the water treatment system, when the cartridge is installed. An accumulating vessel is placed in fluid communication with the first outlet port and the second inlet port for storing water that has been treated by the first filter element prior to treatment by the second filter element. The filter apparatus includes an electro-chemical anti-contamination device in fluid communication with the second outlet port and downstream of the second filter element for inhibiting the retrograde growth or the migration of microbes, bacteria, etc. into the filter apparatus by way of the faucet.
